DataSet of thermodynamic analysis of a liquid air energy storage system with off-peak electric heat storage and reutilization
Listed in ScienceDB
As a large-scale energy storage technology, liquid air energy storage (LAES) can effectively improve the stability and quality of power grid.
Description
However, the traditional LAES has low cycle efficiency, high initial investment and low economic benefits. In order to improve the system performance, a LAES system based on off-peak electric heat storage and high temperature preheating of turbine inlet air was proposed.
The thermodynamic characteristics of the LAES system were analyzed, and the energy analysis, exergy analysis and economic evaluation were carried out. Combined with off-peak electric heat storage, the power generation during the peak time by the LAES system can be significantly increased, and the economy of the LAES system can be effectively improved with the peak-valley electricity price difference, especially in areas where the price difference is obvious.

The results will be beneficial for the application and promotion of the LAES technology.
